You have an
incoming call,
but do not
receive any
call informa-
tion. Someone picked up a tele-
phone on the same phone
line before the CID recorded
the call record. This is not a

Check that the CID is cor-
rectly and securely con-
nected.
Call your phone company to
verify that your Caller ID ser-
vice is active.
